    Abstract: A gas discharge tube (GDT) can include first and second electrodes each including an edge and an inward facing surface, such that the inward facing surfaces face each other. The GDT can further include a sealing portion implemented to join the edge portions of the first and second electrodes to form a chamber between the inward facing surfaces of the first and second electrodes. The GDT can further include an electrically insulating portion implemented to provide a surface that covers a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path between the first and second electrodes includes a path on the surface of the electrically insulating portion.

    Abstract: A chip varistor includes an element body exhibiting varistor characteristics, internal electrodes containing a first electrically conductive material, and an intermediate conductor containing a second electrically conductive material. The intermediate conductor is separated from the internal electrodes in a direction in which the internal electrodes oppose each other, and is disposed between the internal electrodes. At least a part of the intermediate conductor overlaps the internal electrodes in the direction in which the internal electrodes oppose each other. The element body includes a low resistance region in which the second electrically conductive material is diffused. The low resistance region is located between the first and second internal electrodes in the direction in which the first and second internal electrodes oppose each other.

    Abstract: Devices and methods related to metal oxide varistor (MOV) having modified edge. In some embodiments, a MOV can include a metal oxide layer having first side and second sides, first and second electrodes implemented on the first and second sides of the metal oxide layer, respectively, with each electrode including a laterally inner portion and an edge portion. The edge portion of at least the first electrode can have a flared profile. In some embodiments, two of such MOVs can be joined to provide a sealed chamber defined by shapes of the first sides of the respective metal oxide layers and enclosing a gas therein, such that the sealed chamber with the gas and the first electrodes of the two MOVs form a gas discharge tube (GDT).
